Because news of its SPAC-fueled public market debut wasn’t enough, Rocket Lab also unveiled a new class of rocket it has in development on Monday. The launch vehicle, called Neutron, will be able to carry 8 metric tons (around 18,000 lbs) to orbit, far exceeding the cargo capacity of Rocket Lab’s current Electron vehicle, which can host only around 660 lbs. Neutron will also have a fully reusable first-stage, designed to launch on an ocean landing platform, not unlike SpaceX’s Falcon 9 booster.

Rocket Lab says that Neutron will be designed to service increased demand from customers launching large multi-satellite constellations. The heavier lift will mean that it can take more small satellites up at one time to get those constellations in orbit more quickly. Its cargo rating also means it should be able to deliver up to 98% of all currently-forecasted spacecraft launching through 2029, according to Rocket Lab, and provide resupply services to the International Space Station. Rocket Lab also says it’ll be capable of human spaceflight missions, indicating an ambition to make it the company’s first human-rated spacecraft.
